In this study, the use of porous resins as adsorbents for the removal of tylosin from aqueous solutions was evaluated. The effectiveness of the resins (macroporous resin XAD-4, hypercross-linked resin MN-202, and aminated polystyrene resin MN-150) was compared with commercial hydroxylated multiwall carbon nanotubes (H-MWCNTs). Similar patterns of pH-dependent adsorption were observed despite the different surface properties and pore structures of the three resins, implying the importance of the tylosin molecular form in the adsorption process. Tylosin adsorption onto the four adsorbents showed different ionic strengths and temperature dependence consistent with the tylosin speciation and corresponding adsorption mechanism. The adsorption of tylosin onto the XAD-4 and MN-202 is mainly controlled by the intermolecular interactions between the matrix of the adsorbents and the tylosin molecule, whereas specific bonds among multiple surface functional groups are the predominant contributors to MN-150 and H-MWCNTs. The pore size is the key parameter in tylosin adsorption onto the surface of the adsorbents. The adsorption kinetics of the four adsorbents followed the pseudo-second-order model. The adsorption isotherm data well fit the Langmuir models, indicating surface coverage by a monomolecular layer.
